COMPRESS'ED-AIR SPRAY.

SPECIFICATION forming part of Iuetters Patent No. 721,752, dated March 3, 1903.

Application led July 22, 1901. Serial No. 69,170. (No model.)

To all whom, t may concern,.-

Be it known that I, LoYD SoEUGGs, residing at Omaha, in the county of Douglas and State of Nebraska, have invented certain useful Improvements in Compressed-Air Sprays; and I do hereby declare that the followingis a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, referencev being had to the accompanying drawings, whichform a part of this speciiication.

This invention relates to a new and novel improvement in compressed-air sprays.

The aim of my invention is to provide a coinoperated air-spray adapted to be used in theaters, churches,.railwaycars, barbershops, dentists ofices, and, in fact, wherever it may be desired to have a cool spray of air.

In the accompanying drawingsI have shown in Figure l a side View of acoin-controlled compressed-air sprays Fig. 2 shows a side view thereof with portions removed. Fig. 3 shows a detail of thel movable and adjustable head,

while Fig. 4 shows an enlarged detail disclosing the arrangement of the air controlled valve.

My invention embodies, essentially, a housing A of any suitable material and conforma-` tion, which is inclosed by means of a glass front C, held by means of the frame B. EX- .Y

housing H is the valve-stem 15 of any ordi-- nary construction. This valve projects, how--` ever, beyond the valve-housing H upon both sides and has one of its ends provided with. the slot fr, While the remaining extending portion of this valve l5 has secured to it, by means of a suitable screw 17, a coil-spring 14, so that this Valve I5 is in a normally closed condition and being held under-spring tension by virtue of the coil-spring 14, which has its remaining end coiled about a pin e, secured to the valve-housing H, as is shown in Figs. I and 2. f

Secured to the valve I5 is an incised disk 16, as shown more clearly in Fig. 2, which is provided with the removed portion Z, so as to form a seating into which normally drops and is held the springoperated plungerstem c.

Extending upward and beyond the housing A from the valve H is the pipe 7, which pipe 7 above is provided with the terminal valvehousing et, Within which is held the valve 3, which valve is provided with the removed portion b and enters into the hollow perforated head 2, provided with the perforations d, as is disclosed in Fig. 1.`

It will be noticed in referring to Fig. 3 that the head 2 is secured at an angle to the stem 3, so that this stem 3 may be revolved to bring the face of the head 2 into various positions, so that the air-spray passing out of the openings a may be directed straight ahead or upward or downward. The valve 3 of this movable and adjustable head 2 is secured by means of the screw 6 and the interposed Washer 5 as is usual in ordinary valve construction.

' Extending fromthe tube 7 is the down- `wardly-turned elbow 8, and. this elbow Sis provided witha metal frame 9, within which is held the glass tube g, the metal frame 9 l being in the form of a tube provided with the removed portions 1l, as is clearly shown. This glass tubei is in air communication by means of the elbow 8 with the tube or pipe 7. Working Within the glass tube t' is a piston IO, which piston is suitablysecnred to the stem c, which stem c extends through the terminal cap I, closing the lower end of the glass tube 'L' and suitably secured to the frame 9. Passing through this stem c below the cap l is a pin 13, and interposed between the piston IO and the cap l is an-ordinary spring l2 to normally force this stem c upward to hold this stem c out of engagement with the incised disk I6, which forms a-locking cam or keeper by means of which the air-supply valve l5 may be held in an open condition IOO come 'into engagement with the pins 23 and 23 to check the valve 15 in its open and closed position.

Positioned adjacent to and in alinement with the slotted end of the valve 15 is a key 25, which has a hub 25', extending through the side of the housing A, and this hub is provided with a registering incision, as indicated in dotted lines in Fig. 1, similar to the end of the stem 15, the incision of which is clearly shown in Fig. 4. The width and distance of these slots and their relative position are so adj usted that they nicely actuate a coin of a certain value, as indicated at V in Fig. l. Positioned below the slotted end of the valve l5 and the slotted hub 25 are the pins 30 30, which are so positioned that they just hold the coin or token between them, so that anything smaller than the desired coin or token will drop between these pins 30 30, while a chute D, which terminates just above these slotted members l5 and 25', will not permit any coin or token of a larger size to be inserted into the chute D, extending beyond the housing A, as shown. Positioned below the coin-holding members 15 and 25', is a suitable receptacle K, into which the coins eventually drop.

My air-spraying device may be attached to the back of a chair or may be held upright in a suitable position by means of the supply-pipe F, which forms a standard and holder for the housing A, and this pipe F may be provided with a suitable foot, so that the same may be portable, permitting its being moved from place to place Within certain limits.

Connected to the pipe F is a suitable airsupply pipe leading from a tank within which the compressed air is held, the air being conducted to the pipe F by any suitable means.

Where the instrumentalities have been properly constructed, the operation of my device would be as follows: The air-supply Valve H would be held in a normally closed position because of the spring 14. A suitable coin or token would then be placed Within the chute and in passing through the same would fall within the incisions within the end of the valve 15 and the hub 25', being supported by means of the pins 30. As soon as the coin had found lodgment it would form a connection between the handle 25 and the valve l5, and the operator would then turn the valve to open the same to permit the escape of the air through the pipe 7 and perforated head 2. As soon as the valves were turned a suitable distance the air would rush through the elbow 8 and into the cylinderg and exert a pressure upon the piston 10 to counteract the tension of the spring l2, and so force the end of the stem c into engagement with the incised keeper 16 to hold the valve 15 in an open condition, so that the air would readily escape through the perforations a. As soon as the operator released the handle 25 the coin would fall out of the slots a: into the receptacle K below. The operator wouldthen adjust the head 2 at a proper angle, so that the air would be blown into the operators face.

In referring to Fig. 3, it will be noticed that the stem 3has the removed portion b, so that the air may readily pass through the opening b and into the head 2. In tilting the head 2, however, in one position the solid portion of the valve 3 would come over and close the opening within the valve 4, so that by means of this movable and adjustable head 2 the air may be cut oif, if desired.

In equipping a theater, for instance, with 'my air-spraying device the housings A could be secured to the backs of all chairs excepting, say, the rst row, so that the forward chair within each row would act as a standard for the rear chair, and the air could be conducted to the tubes F by any suitable means. A main cock would be placed within the main supply-pipe and this be turned on so that all the tubes F would supply with air. After the performance or at the conclusion of any certain time the main supply-cock would be turned off, which would cut off all the air-pressure within the tubes F, so that the pressure above the piston lO would be removed, so that each piston' 10 would at once be thrown upward to release the valves 15 to cut olf the air'supply, so that all the connected spraying apparatus would be instantly disconnected and locked in turning off the pressure at a suitable main supply-point. As soon as the pressure were again turned on the apparatus would all be in condition to be again operated by means of the coin.

I do not wish to be understood as desired to confine myself to the exact construction and arrangement of the instrumentalities as shown, as certain changes may be made Without departing from the spirit of my invention.

Having thus described my said invention, what I claim as new, and desire to secure by United States Letters Patent, is-

In a spraying device of the character described the combination, with an air-supply pipe, of a valve secured intermediate of the ends of said pipe, a spring secured to said valve to normally close thev same and hold the same underspring tension, aseating within said valve, a branch pipe extending from aforesaid pipe, a piston working within said pipe provided with a projecting stem, said stern being adapted to work into aforesaid seating of aforesaid valve, a spring to normally force said piston inward to hold aforesaid stem normally out of engagement with said seating, and means to turn aforesaid valve against its spring tension, said instrumentalities being arranged to operate substantially in the manner set forth.
